Is there supposed to be multiple choice answers
Here are the answers in order:
1. During a physical change the substance changes physically.
2. The law of conservation of mass is a law stating the conservation of mass cannot be higher than 46mg or lower than 32mg.
3. A hypothesis is a guess that you make before completing a science experiment, it can be considered a law because it is important to know why you are making the guess.
4. During a chemical change the mass is changing colors. This is a representation of a chemical change.
5. Oil is a non-renewable resource, so it cannot demonstrate the conservation of mass.
6. When the color of the substance has changed or when it explodes.
7. Reactants are the objects that react when in a chemical change.
8. If you follow the rule of not going higher than 46mg and not lower than 32mg then it will automatically follow this law.
Chemical Reactions Part One Video:
1. mass
2. erupt-ant
3. reactant
4. object
5. mixtures
6. molecules
7. color changed
Questions again:
1. A chemical reaction
2. A physical change
3. Because if it is no higher than 46mg and no lower than 32mg then it will follow on it's own.
The movement of the ocean and sea waves in a direction is called the ocean currents. Ocean currents can bring cold water, which cools the land and atmosphere.
<h3>What are the effects of ocean currents?</h3>
Ocean currents are the movement of the oceanic waves by the influence of the gravitational forces that can affect the atmosphere and the climate of the region.
Oceanic currents are capable of carrying cold water from polar areas to the regions of the equator resulting in a cooling atmosphere over the geosphere.
Therefore, option B. oceanic currents carry colder air to the warmer regions.
